AD8345-EVAL datasheet

 

Description:

The AD8345 is a silicon RFIC quadrature modulator, designed for use from 140 MHz to 1000 MHz. Its excellent phase accuracy and amplitude balance enable the high performance direct modulation of an IF carrier. The AD8345 accurately splits the external LO signal into two quadrature components through the polyphase phase splitter network. The I and Q LO components are mixed with the baseband I and Q differential input signals. Finally, the outputs of the two mixers are combined in the output stage to provide a single-ended 50 Ω drive at VOUT.

Features

1. 140 MHz to 1000 MHz operating frequency
2. +2.5 dBm P1dB @ 800 MHz
3. −155 dBm/Hz noise floor
4. 0.5 degree RMS phase error (IS95)
5. 0.2 dB amplitude balance
6. Single 2.7 V to 5.5 V supply
7. Pin-compatible with AD8346 and AD8349

Applications

1. Cellular communication systems
2. W-CDMA/CDMA/GSM/PCS/ISM transceivers
3. Fixed broadband access systems LMDS/MMDS
4. Wireless LAN
5. Wireless local loop
6. Digital TV/CATV modulators
7. Single sideband upconverter

SG3527AJ Datasheet PDF – Regulating Pulse Width Modulator

Part Number: SG3527AJ

Function: Voltage Mode PWMs

Package: DIP 16 Pin Type

Manufacturer: Microsemi Corporation

Pinouts:

SG3527AJ datasheet

 

Description:

The SG1525A, SG1527A, SG3527AJ series of pulse width modulator integrated circuits are designed to offer improved performance and lower external parts count when used to implement all types of switching power supplies. The on-chip +5.1 V reference is trimmed to ±1% initial accuracy and the input common-mode range of the error amplifier includes the reference voltage, eliminating external potentiometers and divider resistors.

Key Features:

1. 8V to 35V operation

2. 5.1V reference trimmed to ±1%

3. 100Hz to 500KHz oscillator range

4. Separate oscillator sync terminal

5. Adjustable deadtime control

6. Internal soft-start

7. Input undervoltage lockout

8. Latching P.W.M. to prevent multiple pulses
